Bulldozer blade control lever
The bulldozer blade is a robust blade used to push large
quantities of dirt or rubble. It is primarily used to move
heavy materials. The bulldozer blade control lever
(1) is
located on the right hand console. Position (A) FLOAT is
the only position that the lever will remain in without the
operator holding the lever. The blade will stop, and the
lever will return to neutral or the HOLD position in any
other position when the lever is released.

Float
FLOAT (A) is a detent position. When in the FLOAT po-
sition, the blade can follow the level of the ground without
movement of the control lever.
Lower
Push the control lever forward (B) to LOWER the blade.
The control lever must be held in this position in order to
lower the blade. When the lever is released, it will return
to the HOLD position.
NOTE: A quick drop feature allows the blade to lower
quickly. The further the joystick is moved forward, the
more quickly the blade moves. To activate the quick drop,
move the joystick to the end of blade down stoke before
the float detent feel point.
Raise
Move the control lever back to the RAISE (C) position to
lift the blade. When the control lever is released, it will
return to the neutral or HOLD position.
Hold
The blade will stop moving in the HOLD position. When
released, the control lever will return automatically to the
HOLD position. You must manually move the control
lever from the FLOAT position to the HOLD position.
